Emily Post and Miss Manners have written volumes about how to kindly treat your guests.

Apparently, none of the boys on the Davis High tennis team have read any of it.

In dispatching Golden Valley, 9-0, the Blue Devils sent their visitors home empty-handed on Tuesday afternoon at the Davis High Tennis Complex.

It was a fine how-do-you-do for a school that drove 258 miles round trip only to be routed in the second round of the Sac-Joaquin Section playoffs.

“Tris (Dutta) is having his moments,” DHS coach Dale Hersch said of his No. 2 singles player who vanquished Thomas Becker, 6-2, 6-4. “He’s a free swinger. He goes out there and sometimes forgets who he’s playing.

“I was very impressed with him closing that out. He’s someone who kinda lets it go and all of a sudden he’s winning into the third set.”

Meanwhile, Davis No. 1 Dan Segedin fell behind GV’s Cesar Nava, 3-0, but rallied before losing his first set, 7-6 (7-5). Segedin went on to take the second set, 6-4, before capturing the tiebreaker, 10-8.

Hersch praised the effort of Segedin who, like Nava, won a league championship. Hersch thinks the two could meet again in the section individual tourney later this week.

Juniors Dutta and Segedin were the final two matches going a half-hour after the rest of the Devils had ousted their competition.

Early on, it was locals Alex Chen and James Cole making short work of Bee Lee and Za Thao, 6-0, 6-0, while Scott Lucio and freshman Cooper Hosley sent Abdullah Kounda and Lohinh Sac Lee packing, 6-0, 6-1.

With the writing on the wall, No. 6 Blue Devil Jasper Murphy took care of business against Wallison Ziang, 6-0, 6-0 — the same score by which Chase Kellison closed out Scott Smith to secure the match for DHS.

Bob Li, in a dominating 6-0, 6-2 showing against Yee Theo, joined the courageous Louis Pak in the clubhouse (6-4, 6-0 against Adrian Garcia) with singles victories.

Pak battled a groin injury. After a shaky start, he collected himself and created pin-point volleys and terrific backhand points. Hersch said the injury, which has plagued Pak for a while, may have helped the junior’s accuracy.

The Cougars came into the ambush with a 9-3 dual match record. They finished second in the Central California Conference and defeated Georgi (Modesto), 7-2, in the first round. Delta Valley Conference champ Davis received a first-round bye.

Now, the Blue Devils (12-4, 8-0 in DVC) await word on whether they meet Oak Ridge or West (Tracy) on Monday. Site and time are to be determined.
